Specification of Letters Patent.

Patented Mar. 14, 1916.

Application filed July 15, 1915., Serial No. 39,940.

To allwhom it may concern:

Belt known that 1,;Donn W'oon, a citizen of the United States, residing in the city, county, and State of New York and whose post-office address is at 98 Mornlngside avenue, in said city, have invented certain new, and useful Improvements in Devices for Mixing Liquids, of which the following isa specification.

My improvements relate to devices which are generally employed for the mixing or compounding of liquids in receptacles, as glasses and in like ways, and thespecial objectsof'my improvement are to dispense with themechanically operated mixing devices, such as by motor, clock work, and intricate gearing, andi to simplify andeconomize in, th v COnstruction of such a device and for assemblage and dismemberment of the device for. cleaningpurposes.

One, of the special. features of my invention is the provision of an apertured dasher cup so designed that, upodits downward stroke into the liquid mass, it will forcethe more or less solid or undissolvedl contents oftheliquidmixture upwardly through the of liquid and content with it, thereby. rap

idly and elhciently securing an intimate mixture.

My invention consists in the novel details of construction and combination of parts hereinafter described and further pointed out in the claims.

In the drawing forming part of the specification, Figure l is a perspective elevation of a device embodying my improvements; Fig. 2 is a sectional elevation taken centrally through the device, somewhat enlarged, parts being broken away to save room 1n illustration; and Fig. 3 is a plan view of the dasher cup.

Throughout the various views of the drawings, similar reference characters designate similar parts.

My invention is capable of embodiment in more than one form. The one herein shown, however, has beendetermined to be practical and efiicient for the purposes of my invention.

At 1 is a suitable base and at 2 a standard or pillar erected thereon, the latter being preferably square or rectangular 1n cross section.

At 3 is a sliding frame consisting of the arms 4, 5, a projection 6 and a squared coll'ar 7. This collar is placed about the pillar 2 and it contains fiat springs 8 which frictionally bear against the sides of the pillar. The pillar and bore of the sleeve 7 being square, the latter cannot turn upon the for mer; at the same time it can be moved up and down unrestrictedly and with it all the parts hereinafter described, which are attached to it. These latter may be bodily removed from the pillar for the purpose of dismemberment, cleansing or repair. The ends of the arms 4, 5, are apertured, as at 9; Between these arms extend a cylindrical casing 10. Through the casing and the apertures 9 in the arms 4:, 5, extends a rod 11; Above the arm 4 the rod is provided with a removable disk 12. l

At 13 is a cup-cap of'usual construction which is designed to lie over glass as l t, and in the usual manner retain the contents in the glass. A stud 15 on the base 1 assists in the positioning of the glass.

cured to its lower end by means of a nut 16 and a screw thread 17 on the rod, a dasher cup 18. This cup is bell-shaped with its open end extending downwardly and is provided with a series of apertures 19, 20, the apertures 19 being preferably circular and disposed adjacent the lower edge of the cup and the apertures 20 being preferably rectangular and upwardly elongated and located intermediate of the crown 21 of the cup and its lower edge 22. The cup may be otherwise apertured, but I prefer the above described arrangement, for the reason that the circular apertures 19 will force the more freely movable solids or non-dissolved ingredients, such as sugar and the like, up through the cup, while the upwardly elongated apertures 20 will allow of a considerable quantity of liquid passing up and through the cup as well as carrying with it other pieces of floating solid material.

Inside of the casing 10 is a coil spring 23 which embraces the rod 11, one end of the spring resting against the upper face of the arm 5, the upper end bearing against a washer 24 which surrounds the rod 10, a pin 25 serving to keep the washer in position.

In the operation of the device, the frame 6 is raised and the glass 14 containing the mixture placed upon the base 1, its lower edge striking the projection 15. Then the frame is lowered until the cap 13 covers and engages the glass for the purpose above described. Particularly the weight of the frame bearing on the cap retains the latter in ,place. By a series of quick blows or thrusts on the disk 12, the dasher mp1s forced down into the liquidgoperating as above described tothoroughly mix and intermingle the contents. After the mixing has been completed, the frame G'is raised so as to' free the glass from the dasher cup and cap 13, the springs 8 holding the frame in its elevated position;

consider my invention as broad as the scope of the claims appended hereto.

Having described my invention, I claim:

1.}In a device of the class described, the. combination with a base, a pillar thereon, a

frame slidable upon said pillar, a rod movable in said frame, a spring for retracting :said rod when the same has been forced 2. In a'device ofthe class described, the i combination with a base, an upwardly extending pillar mounted on said base, aframe said frame, 'a hol low cylindrical casing ex- .movableon, said pillar, a pair of arms on;

tending between said arms, a rodextending through perforations formed in saidarms and through said casing, a spring in said casing surroundii'ig said rod, a stopon said rod against which the upper end of the spring abuts, adasher cup secured tothe lower end of the rod and a cup cap, having an opening through which the rod extends,

between the dasher and the frame. I 3. In adevice of the classdescribed, the

combination with a base, a pillar mounted on said base and extending upwardly therefrom, a. movable frame mounted on said pillar, a pair of arms on said frame, one of saidarms being disposed above the other, a

formed'adjacenttheends of said arms and through the casing, a coil spring within said casing and surrounding said rod, one end of said coil spring resting on the lower arm on the frame, the other end abutting against a pin on said rod and a bell-shaped dasher on the lower end of said rodr 7, p
